Marketing is a swing, and a miss for nostr atm. Hopefully that will change at some point. There has to be a focus on what an end user demands. A quick example of how my business dealt with market demands. My industry is riddled with poor customer service. We read all the bad reviews for companies in our area, and %90 of them were poor customer service. Bad reviews aren’t just people gripping about a company. It’s potential clients telling an industry what they want from an industry. Address that, and you’re king in your industry. You offered something that people want. Does Nostr provide something people want?  How much market research has been done to find out what most potential end users want?  I wouldn’t expect much, or enough has been done tbh. I wouldn’t expect most would care much about privacy, bitcoin, censorship free, or a whole lot of what Nostr provides. That’s not to say those aren’t important. It is to say that if Nostr wants success to a point that it competes then keep all that is good already with Nostr, but more focus should be placed on what  end user demands are. So outside of the Nostr bubble what are people talking about with social media?  What are there complaints, what do they like. What would they improve?  The largest number of those people probably don’t care about what Nostr is currently offering. Nostr needs to know what those people care about, and do that where it doesn’t interfere with its foundational principles. 
You can’t just say it’s superior so everyone will use it. Thats not how things work. I’m a pretty bad ass classical guitarist, but none of you knew that, and a lot of you might not believe me, because I didn’t market myself as such, and who likes classical guitar anyways. Some do for sure, but I’m not grabbing millions of views with it. I might do better to transpose some classical guitar songs over to an instrument that would be more appealing if I were to want a bigger audience, or I might do, and really I am doing in a since what nostr is doing. Just Jamin in my backyard hoping the neighbors will hear me, and call Carnegie Hall to tell them they really need me.
